Fix OpenLineage deprecation warning (#1449)

Openlineage suggests using event_v2 as the new import call. This can be
seen in the source code of openlineage itself for the
[run](https://github.com/OpenLineage/OpenLineage/blob/main/client/python/openlineage/client/run.py)
method.

```
UserWarning: {message : DeprecationWarning('This module is deprecated.
Please use `openlineage.client.event_v2`.'), category :
'DeprecationWarning', filename :
'/home/airflow/.local/lib/python3.10/site-packages/openlineage/client/filter.py',
lineno : 9, line : None}
